Lead Mining in the Northwest Region – Galena History Museum
Lead mining built Galena. While Native Americans had sporadically mined lead for thousands of years, it was the arrival of Europeans that led to the first major mineral rush in U.S. history. Our exhibits document this saga, with original mining tools displayed, as well as a life-size windlass. Windlass in Mining Exhibit.

Galena Mineral
Galena tarnishes to a dull gray. Because lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak. Crystals are common and they usually are cubes, octahedrons, or

Galena
Galena is the most common. Lead ores are usually roasted and then reduced in a blast furnace with coke. Purification is carried out by adding zinc, which removes silver (Parkes process), or by electrolysis in a solution of lead hexafluorosilicate and hexafluorosilicic acid (Betts process). One of the most useful properties of lead is its
